A Case Study On The Differences Of Novice Teachers' And Expert Teacher's Eyes' Visuals Under Technical Support

Hundred years' policy based on education;while the education policy based on teachers.Teachers' professional development has always been an important part of teacher education research.Tcachers' professional development process is also about the teacher from a novice to be an expert.Therefore,through comparative research,we can find the differences between novice teachers and expert teachers in various teaching aspects.Then we could help novice teachers get progress more quickly in professional development.Because of the complexities and multi-causalities of education,how to analyze the teaching behaviors' characteristics deeply in coding system has become a huge problem in today's teacher education research.With the advent of the intelligent age,especially the emergence of intelligent camera glasses,provide a good opportunity to study teaching process from teachers' own perspective.Teachers wear intelligent camera glasses to record the scene videos.Analysis the screen categories from a new perspective to find the differences between expert teachers and novice teachers.At last put forward the development advice has a great significance and value for novice teachers get progress more quickly.On the basis of a large number of relevant literature review,analysis and induction,it is found that the traditional teacher education research is from the perspective of the bystander.However,the study of onlookers would ignore the teacher's ontology and quantitative analysis easily,which is not conducive to a profound understanding on the reasons behind teaching difficulties of novice teachers.In addition,the comparative study of novice teachers and expert teachers focuses on teaching behaviors,teaching efficacies and so on,less research on teachers' teaching perspective on quantitative analysis.In the video analysis's codes,most of them are about teachers and students' interactive language,such as Flanders interactive analysis system,few of the code systems are about screen'content of the video.Drawing on the idea of Flanders analysis method,design the coding system.Record the observed scenes of class with intelligent camera glasses from teacher's subjective perspectives.According to the principles of time-division samples,code and analysis the video screens in four dimensions:classroom area,angle of view frequency,depth of student and frequency of deep interaction between teacher and students in the classroom teaching process.The following conclusions are obtained:(1)Content of the subject aspect:The expert teacher pays more attention to students,while the novice teacher pays more attention to the media;(2)Classroom areas aspect:The expert teacher can balance attention to every region,while the novice teacher has blind spot;(3)Perspective change frequency aspect:The expert teacher' perspective change quickly less,while the novice teacher'perspective easily changes in a short time;(4)Breadth of students and frequency of depth interaction between teacher and students aspect:The expert teacher has a wider range of students and higher frequency of deep interaction than novice teacher.According to the conclusions of the differences between novice teacher and expert teacher,the following suggestions are made to help novice teacher to get progress quickly:(1)Transform the teaching focus from the media to students;(2)Balance the attention to every area of the classroom,especially the area where was in a blind spot before;(3)Keep the eyes' switching be stable.Minimize a rapid eyes' switching in a short time;(4)In the deep interaction with students,teacher should extend the students numbers,as much as possible interact with more students,enhancing the frequency of interaction.
